Matrix4x4::MultiplyPoint
Vector3 MultiplyPoint(const Vector3& v) const
使用矩阵变换一个点。会自动处理 w=1 的齐次坐标变换，适用于位置变换。
参数：
v- 待变换的三维点
返回： 变换后的三维点
线程安全： ✅
复杂度： O(1)
示例：
#include "XCEngine/Core/Math/Matrix4.h"
#include "XCEngine/Core/Math/Vector3.h"
using namespace XCEngine::Math;
Matrix4 transform = Matrix4::TRS(
Vector3(1.0f, 2.0f, 3.0f),
Quaternion::Identity(),
Vector3(1.0f, 1.0f, 1.0f)
);
Vector3 point(1.0f, 0.0f, 0.0f);
Vector3 transformed = transform.MultiplyPoint(point);
// transformed = (2.0f, 2.0f, 3.0f)
